period the patient was in good condition, but was still complaining of 

 hunger. His weight had increased to 50.80 kilograms and the pulse 

 and temperature were normal. 



During the second preservative subperiod some pain was felt in the 

 shoulder, but evidently this bore no definite relation to the diet. Com- 

 plaint was made on December 9 of a very empty feeling in the stomach; 

 otherwise the subject was feeling well. This condition continued 

 throughout this subperiod, with a general feeling that the amount of 

 ration eaten was not sufficient to supply the appetite, and the subject 

 complained frequently of being hungry. 



The third preservative subperiod (November 13-17) began with pulse 

 and temperature normal. The weight had risen to 51.15 kilograms. 

 Complaint was made during the first day of severe pains in the stomach. 

 This continued during the next day, but the subject still complained 

 of being hungry. On the 15th severe pains were felt in the shoulder, 

 but normal conditions were restored on the 16th. On the 17th the 

 pains in the stomach returned, but the other conditions were normal, 

 and at the end of this subperiod the weight of the subject was 51.14 

 kilograms; but the average weight was only 50.96 kilograms. 



The fourth preservative subperiod (November 18-22) began with 

 marked symptoms of hunger after the usual rations were eaten. On 

 the ] 9th constipation was marked and the pains in the stomach con- 

 tinued. On the 20th report was made of very severe pains in the 

 stomach, continuing during the night, and the constipation continued 

 markedly. The general condition was better on the 21st, but the con- 

 stipation continued. On the 22d the subject was belching all the time 

 with acidity of the stomach and indigestion. This subperiod closed 

 with the subject in rather an unfavorable condition, but with an 

 increased average weight, i. e., 51.14 kilograms. 



The fifth preservative subperiod (November 23-27) began with 

 normal pulse and temperature, but with continued belching, indiges- 

 tion, and heartburn, which rendered the subject very uncomfortable. 

 On the 24th these symptoms were ameliorated to a certain degree and 

 he was feeling reasonably well. The symptoms returned, however, 

 with renewed vigor on the 25th, with continued burning sensation in 

 the throat and stomach, especially after meals, and continuing for about 

 two hours. The weight on this day was slightly increased, being 51.54 

 kilograms, the average weight for the fifth subperiod being 51.31 

 kilograms. The end of the entire preservative period found the 

 patient in reasonably good condition, with a strong appetite, pulse and 

 temperature normal, and weight 51.60 kilograms, while the average 

 weight for the period was 50.93 kilograms. 



The first after subperiod began with a rapidly restored normal con- 

 dition, which continued until December 1, when the patient was attacked 

 with another severe cold, the temperature having risen at the dinner
